Cached SLM to reduce the PAPR of OFDM signal
Selected mapping (SLM) is one of the most well-known peak-to-average power ratio (PAPR) reduction techniques proposed for the orthogonal frequency-division multiplexing (OFDM) systems. The main drawback of the conventional SLM scheme is high computational complexity because of numerous inverse fast fourier transform (IFFT) operations when transmitting one OFDM signal, which may hinder its wide ...
متن کاملAn Improved SLM Technique For PAPR Reduction In OFDM Systems
Orthogonal Frequency Division Multiplexing (OFDM) is widely used as a standard modulation for various high data rate wireless communication systems. It is worked by converting high data rate streams into a number of parallel low data rate streams. OFDM has many advantages over single carrier modulation systems. Some of these advantages are robustness to frequency fading channels, high transmiss...
متن کاملJoint Non Linear and Distortion based PAPR Reduction Technique for Optical OFDM Systems
Orthogonal Frequency Division Multiplexing (OFDM) has emerged as a promising modulation technique for high speed optical systems as it reduces intersymbol interference and offers high spectral efficiency. But it has an inherent drawback of high Peak to Average Power Ratio (PAPR) due to multiple subcarriers which makes it sensitive to non linear effects. Different techniques have been proposed f...

15 صفحه اولReview of Non-Linear Transform based Techniques to Reduce the PAPR in OFDM Systems
Orthogonal Frequency Division Multiplexing (OFDM) is a spectrum efficient multicarrier modulation scheme for high speed communication systems. OFDM provides robustness against multipath fading channels, but is sensitive to nonlinear effects due to the high Peak-to-Average Power Ratio (PAPR) of the transmitted signal. The reduction in PAPR is desirable in order to obtain power efficiency and to ...
